Abstract
We present a protocol for error characterization and its experimental implementation with 4 qubits in liquid state NMR. The method is designed to retrieve information about spatial correlations and scales as , where is the maximum number of qubits that have non-negligible interaction. We discuss the practical aspects regarding accuracy and implementation.
